Description
Technical field
The present invention relates to a kind of elastic damping components, particularly a kind of resilient sleeper-bearing.
Background technology
At present China's overwhelming majority railways be all mixed running circuit, even if nowadays develop high-speed railway rapidly, also divide the difference periods and run respectively passenger traffic and shipping fermenting, thereby line resource is fully used, and bring into play to greatest extent its economic worth.Because the bogie structure that passenger and freight adopts is different, axle heavy different, car body is different, the weight of carrying etc. is all different, so also different to the rigidity requirement of the resilient sleeper-bearing using in track circuit.But same circuit conventionally only can be used same resilient sleeper-bearing (the resilient sleeper-bearing here can refer under resilient sleeper-bearing under rail, iron chair resilient sleeper-bearing or sleeper with resilient sleeper-bearing etc.), single, the horizontal and vertical rigidity of its vertical stiffness can not flexible modulation, when in the face of different operation operating mode, the improvement of the reduction of track structural vibration intensity, wheel-rail interaction is had to larger limitation.Construction along with heavy haul railway, high-speed railway and Line for Passenger Transportation, the freight volume that causes mixed running circuit to be born is heavier more greatly, applying working condition is further severe, the effect of resilient sleeper-bearing is also more remarkable, also higher to the rigidity requirement of resilient sleeper-bearing, if according to the rigidity of bad working environments design flexibility backing plate, can make the cost of production of resilient sleeper-bearing high, and the effect of vibration damping is not necessarily best; If according to looser operating condition design resilient sleeper-bearing rigidity, may cause the problems such as life-span reduction, turnover rate rising of resilient sleeper-bearing, therefore, resilient sleeper-bearing design also has very large technological innovation space.
The design scheme of existing resilient sleeper-bearing is more, but has three essential characteristics: the basic structure of resilient sleeper-bearing is plate body, be arranged in projection, groove or hole on plate body (one or both sides); The projection, groove or the hole that are arranged on plate body are discontinuous layout substantially, and the surface of the projection on plate body, groove or hole formation is in same level; The material of resilient sleeper-bearing is configured to the combination of certain macromolecular material or certain several macromolecular material.
Existing resilient sleeper-bearing is designed with following shortcoming: because the projection on plate body, groove or hole are discontinuous layout substantially, so can not regulate continuously flexibly horizontal and longitudinal rigidity; Because the surface of projection, groove or the hole formation of resilient sleeper-bearing is in same level, so vertical, can not realize linear Stiffness design; Therefore, when circuit carrying changes or when line condition changes, existing resilient sleeper-bearing is because vertical stiffness is single, transverse and longitudinal stiffness tuning difficulty, and do not possess high compliance, is especially not suitable for mixed running track circuit; Plate body surface is the resilient sleeper-bearing of discontinuous layout, and manufacturability is more complicated, and cost of production is higher.
